REFLEX RACING RX28 0.3MM CASTER SHIMS (BLACK) RX28A-19

These 0.3mm caster shims can be used in combination with a 0.2mm shim to reduce the slop in your front end.  Due to tolerance, sometimes a 0.2 with a 0.3 allows for less movement on the upper arms.  The difference in caster is negligible, but we recommend using the towards the back.
